Description

Technical Field

[0001] This utility model relates to the field of flame heating device technology, and in particular to a burner. Background Technology

[0002] Currently, the demand for copper and aluminum die-casting parts is constantly increasing in fields such as electromechanical equipment, new energy vehicles, and sanitary ware. The production of these die-casting products requires the use of small furnaces to melt the raw materials. The furnace typically uses a burner to spray flames to heat the material in the crucible within the furnace body to its melting point.

[0003] Furthermore, existing burners typically feature circular flame nozzles. When operating, these circular nozzles have a relatively small contact area between the flame and the furnace body, which is not conducive to fully utilizing thermal energy. Especially when the width (diameter) is limited, it is difficult to install more combustion-supporting injection holes around the circular flame nozzle, hindering the improvement of combustion thermal energy utilization, and further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, the present invention aims to provide a burner in which the cross-section of the burner body and the flame outlet is designed in a waist-shaped manner, allowing for the placement of more combustion-supporting nozzles around the flame outlet, thereby improving combustion efficiency and maximizing energy utilization.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A burner includes a burner body with a gas inlet connected to a gas control valve via a gas inlet pipe. The burner body also has an auxiliary gas inlet connected to an auxiliary gas control valve via an auxiliary gas inlet pipe. A gas distribution plate is located within a cavity of the burner body, with its inlet hole connected to the gas inlet via a connecting pipe. The output end of the gas distribution plate has a gas nozzle. An auxiliary gas output plate is located on the input side of the gas distribution plate. The auxiliary gas output plate isolates an auxiliary gas input distribution cavity within the rear cavity of the burner body. This auxiliary gas input distribution cavity communicates with the auxiliary gas inlet. The output end of the auxiliary gas output plate has an auxiliary gas nozzle communicating with the auxiliary gas input distribution cavity.

[0006] Furthermore, the output end of the burner body is provided with a flame nozzle, and the vertical cross-section of the burner body and the flame nozzle is waist-shaped.

[0007] Furthermore, the gas distribution plate and the gas-supporting output plate are elongated structures that match the waist-shaped cavity of the burner body.

[0008] Furthermore, the burner body is equipped with an automatic igniter and a flame detector. The ignition end of the automatic igniter extends through the auxiliary gas output plate to the vicinity of the gas injection hole. The gas distribution plate and the auxiliary gas output plate are equipped with flame detection holes corresponding to the flame detector. The gas control valve, auxiliary gas control valve, automatic igniter, and flame detector are connected to the controller.

[0009] Furthermore, the flame detector is an ultraviolet flame detection device.

[0010] Furthermore, the gas injection holes include multiple ones, and the gas distribution plate is provided with a cavity or channel communicating with the input hole, and the cavity or channel is further connected to the multiple gas injection holes.

[0011] Furthermore, the burner body is provided with mounting wing plates on its outer side.

[0012] This utility model has the following beneficial effects: 1. This utility model improves the burner structure by designing the vertical cross-section of the burner body and the flame outlet as a waist-shaped hole. This allows for the installation of more gas injection holes and combustion-supporting gas injection holes in the burner body, resulting in a wider combustion heating surface, producing a higher temperature flame, improving combustion thermal efficiency, and making full use of energy.

[0013] 2. The gas distribution plate and auxiliary gas output plate set in the burner body of this utility model facilitate the uniform delivery of gas and auxiliary gas, so that the gas and auxiliary gas can be mixed more fully, ensuring more complete combustion of gas. The combustion flame is more convenient for heating after being ejected from the waist-shaped flame nozzle.

[0014] 3. In addition to being suitable for furnace heating, the burner of this utility model is also suitable for heating and drying in the fields of agricultural products, food, chemical pharmaceuticals and other industries. Attached Figure Description
